Depends on how much processor you have.Some of the newer progs were designed around ASIO drivers. RB being more designed around MME is quite processor intensive.This is becoming less of an issue as time passes and processors become faster but if you're running an older machine you may have issues. If you do just go back to ASIO.There are only 3 resons you need ASIO
1.Playing a software synth in real time with a controller
2.Using effects that can be heard during recording
3.Access to multiplt ins/outs if restricted by your sound card. Otherwise no advantage to ASIO.
